Text in English: Both terms can be used in a general sense for everything on their side of the river, but are often used in a much narrower sense where Puxi is the older (since the 19th century) central part of the city and Pudong the mass of new high-rise development across the river since the 1980s.
Translation of the previous text to Swahili (individual language):
Maneno haya mawili yanaweza kutumiwa kwa maana ya jumla kwa kila kitu kando ya mto, lakini mara nyingi hutumiwa kwa maana nyembamba ambapo Puxi ndiye mzee (tangu karne ya 19th) katikati mwa mji na Pudong wingi wa mpya juu -Maendeleo ya mto tangu 1980s.
